In a multiplatform kernel that includes both pxa and mmp, we get a link
failure from the clash of two pxa_register_device functions.
Rename the one in mach-mmp to mmp_register_device, along with with the
rename of pxa_device_desc.

Let's move cputype.h away from mach-mmp/ so that the drivers outside that
directory are able to tell the precise silicon revision. The MMP3 USB OTG
PHY driver needs this.

This is to replace the USB PHY initialization code (pxa_usb_phy_init(),
pxa_usb_phy_deinit()) with a proper PHY driver.

Use a proper PHY driver, instead of hooks to a board support package.

This variable may be used by some devices that each have their

The mach/*.h headers are now inaccessible to any external code,
so we can move them all into the mach-mmp directory itself
and remove the subdirectories.
A few headers are not used at all, so we remove them here.

The USB host drivers need platform data to be defined on
pxa168 and pxa910, but the conditionals used in the devices.c
file only work if the drivers are built-in. This patch
fixes the definition by changing the #ifdef to #if IS_ENABLED(),
which works both for built-in and modular Kconfig symbols.
I found one specific problem using 'randconfig' builds, but
for consistency, this patch uses IS_ENABLED() for all Kconfig
symbols in these three files.

"""The Marvell® PXA168 processor is the first in a family of application

1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core,
there are many enhancements like instructions for flushing the
whole D-cache, and so on
2. Clock reuses Russell's common clkdev, and added the basic support
for UART1/2.
3. Devices are a bit different from the 'mach-pxa' way, the platform
devices are now dynamically allocated only when necessary (i.e.
when pxa_register_device() is called). Description for each device
are stored in an array of 'struct pxa_device_desc'. Now that:
a. this array of device description is marked with __initdata and
can be freed up system is fully up
b. which means board code has to add all needed devices early in
his initializing function
c. platform specific data can now be marked as __initdata since
they are allocated and copied by platform_device_add_data()
4. only the basic UART1/2/3 are added, more devices will come later.
